E4M2: Back to Base X (2002 A Doom Odyssey)

E4M2: Back to Base X is the second map in episode The Search for Stephanie of 2002 A Doom Odyssey, or episode Torment Ultima in the 10th anniversary edition. In the latter, a few minor geometry changes were made and one radiation suit was added. The level was designed by Anthony Soto (Swedish Fish) and uses one of the following music tracks: "Popdoom" (ZDoom-only), "Mechanical Sadness" (ZDoom-only for 10th ed.) or "Spirit world II", all of which were composed by Paul Corfiatis.

Secrets

 * 1) Go towards the switch south of the rocket launcher, which will also cause the blocks around you to lower and bar you from returning in that direction. Run in either direction around to the computer terminals, and go towards the teleporter where the partial invisibility resides before it rises (north from the switch). When you teleport, jump to the ledge below to get a backpack and a megaarmor. You can then jump to the other ledge to get a box of ammo and a computer area map. Note that you can get only four tries to reach the teleporter with partial invisibility, as there are only four linedefs that trigger the lift, and each of them only operates once. The linedefs are 1012, 1013, 1023, and 1026, for reference. (sector 1)
 * 2) Lower the red bars with the red switch and drop into the nukage, picking up a radiation suit before you do so. Head south, then west, then south at the next fork, then flip the switch here. Backtrack north and east to find two openings leading to the same room. There is a slightly misaligned part of the northern wall here with a medikit in front of it. Open it and take the lift up to reach a green armor and a berserk pack. (sector 15)
